According to studies, researchers found that people said that least desirable breath smell in a kissing partner was cigarette breath. Also, the survey found that 70% of people said they don't even want to talk to someone who has just smoked a cigarette.

Cigarettes ranked higher than garlic, Marmite, onions, beer, pickled onions, fish, curry, coffee and unbrushed teeth as the least desirable breath smell. One of the researchers discussed how much of a big deal halitosis was in dealing with personal situations. The researcher also mentioned that bad breath (i.e. garlic breath) may make a difference in whether or not a person lands a job.

Also, only 40% of people were brave enough to tell someone else that they had bad breath.
